Description

Die Erfindung betrifft ein Verfahren zur Rückgewinnung von Wärmeenergie bei der Vulkanisation eines Fahrzeugreifens.The invention relates to a method for the recovery of heat energy in the vulcanization of a vehicle tire.

Die Reifenvulkanisation erfolgt in Heizpressen, bei der der Reifenrohling in geeignete Formsegmente eingesetzt und unter Einwirkung von Wärme sowie Druck vulkanisiert wird. Auf der Reifeninnenseite wird ein flexibler Balg an den Reifen angelegt, der mit einem Heizmedium beaufschlagt wird und auf diese Weise dem Reifenrohling von der Innenseite die notwendige Vulkanisationsenergie zuführt.The tire vulcanization is carried out in heating presses, in which the green tire is inserted into suitable mold segments and vulcanized under the action of heat and pressure. On the inside of the tire, a flexible bellows is applied to the tire, which is acted upon by a heating medium and in this way supplies the required vulcanization energy to the green tire from the inside.

Als Heizmedium wird in der Regel ein Heißwasserdampf eingesetzt, welches über ein Rohrleitungssystem dem Innenbalg zu- und wieder abgeführt wird. Nach der Reifenvulkanisation wird der Heißwasserdampf über ein Abluftrohr nach draußen abgeführt.As a heating medium, a hot steam is usually used, which is connected via a piping to the inner bellows and discharged again. After the tire vulcanization the hot steam is discharged via an exhaust pipe to the outside.

Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren zu schaffen, bei dem die im Heißwasserdampf enthaltene Wärmeenergie auf einfache Weise und mit einer hohen Effektivität zurückgewonnen werden kann.The invention is based on the object to provide a method in which the heat energy contained in the hot steam can be recovered in a simple manner and with high efficiency.

  5. e) Abführen des abgekühlten Wassers aus dem Wärmetauscher,
  6. f) Rückführen des abgekühlten Wassers zum Dampfkondensator,
    wobei das Wasser im Wesentlichen im Kreislauf geführt wird und am Wärmeaustauscher die abfallende Wärmeenergie entnommen und einem Verbraucher zugeführt wird.

Auf diese Weise kann insbesondere die Öko-Bilanz von Reifenfabriken wesentlich verbessert werden. Außerdem wird durch das Verfahren der Prozess für die Reifenvulkanisation in keinster Weise beeinträchtigt, wobei gleichzeitig ein Großteil der eingesetzten Wärmemenge mit einem hohen Wirkungsgrad zurückgewonnen werden kann.An advantage of the invention is that with the method, the heat energy contained in the hot steam can be recovered in a simple manner and with a high degree of effectiveness. In this way, in particular the eco-balance of tire factories can be significantly improved. In addition, the method of the process for tire vulcanization is in no way affected by the process, while at the same time a large part of the amount of heat used can be recovered with high efficiency.

In einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Dampfkondensator mehrstufig mit übereinanderliegenden Wasserberieselungs-Vorrichtungen ausgebildet ist.In an advantageous development of the invention, it is provided that the steam condenser is designed in multiple stages with superimposed water sprinkling devices.

Auf diese Weise wird die im Heißwasserdampf enthaltene Wärmeenergie mit einer hohen Effektivität zurückgewonnen.In this way, the heat energy contained in the hot steam is recovered with high efficiency.

In einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Dampfkondensator im Wesentlichen drucklos und im Wesentlichen bei Umgebungsdruck betrieben wird.In a further advantageous embodiment of the invention, it is provided that the steam condenser is operated substantially without pressure and substantially at ambient pressure.

Anhand eines Ausführungsbeispiels soll die Erfindung näher erläutert werden. Es zeigt:

Fig. 1
eine Vorrichtung für die Durchführung des Verfahrens.
Reference to an embodiment of the invention will be explained in more detail. It shows:
Fig. 1
an apparatus for carrying out the method.

Fig. 1 zeigt eine Prinzipskizze von dem Verfahren. An einen zentralen Heißwasserdampf-Kollektor 2 sind mehrere Vulkanisationspressen 1 angeschlossen. Nach der Vulkanisation eines Fahrzeugreifens wird der Heißwasserdampf dem Heißwasserdampf-Kollektor 2 zugeführt. Der Heißwasserdampf-Kollektor 2 ist in der dargestellten Weise an den Dampfkondensator 3 angeschlossen. Der Heißwasserdampf 16 steigt im Dampfkondensator 3 nach oben. Im Dampfkondensator sind übereinanderliegende Ebenen 4, 5, 6 und 7 mit jeweils übereinander liegenden Berieselungsvorrichtungen angeordnet. Fig. 1 shows a schematic diagram of the method. To a central hot water steam collector 2 more Vulkanisationspressen 1 are connected. After vulcanization of a vehicle tire, the hot steam is supplied to the hot steam collector 2. The hot steam collector 2 is connected to the steam condenser 3 as shown. The hot steam 16 rises in the steam condenser 3 upwards. In the steam condenser, superposed levels 4, 5, 6 and 7 are arranged, each with superposed sprinklers.

Über die Berieselungsvorrichtungen wird dem Dampfkondensator abgekühltes Wasser zugeführt. Das abgekühlte Wasser wird in Form von Tröpfchen über die Berieselungsvorrichtungen zugegeben. Der Heißwasserdampf 16 steigt im Dampfkondensator 3 nach oben, wobei das abgekühlte Wasser in Form von Tröpfchen im Gegenstrom geführt wird. Bei diesem Vorgang werden die Wassertröpfchen abgekühlt und der Heißwasserdampf im Wesentlichen in eine flüssige Phase zurückgeführt. Das aufgewärmte Wasser 17 wird über den Schwerkrafteinfluss in den Sammelbehälter 9 geführt. Das Wasser im Sammelbehälter kann eine Wassertemperatur von bis zu 100° C aufweisen. Über die Pumpe 10 wird das aufgewärmte Wasser dem Wärmetauscher 11 zugeführt. Der Wärmetauscher 11 ist mit einem Verbraucher verbunden, bei dem es sich beispielsweise um eine Raumheizung handeln kann. Über die Zuleitung 13 wird das im Wärmetausch abgekühlte Wasser zum Dampfkondensator geführt. Von der Zuleitung 13 gehen einzelne Leitungen zu den Ebenen 4, 5, 6 und 7 ab, die jeweils eine Berieselungsvorrichtung aufweisen. Das abgekühlte Wasser wird über die Berieselungsvorrichtungen im Kreislauf wieder dem Dampfkondensator 3 zugeführt. Auf der Oberseite des Dampfkondensators 3 befindet sich ein Abluftrohr 8. Außerdem ist ein zweites Abluftrohr 14 vorgesehen, welches dann zum Einsatz kommt, wenn beispielsweise der Dampfkondensator instand gesetzt wird.About the sprinklers cooling water is supplied to the steam condenser. The cooled water is added in the form of droplets over the sprinklers. The hot steam 16 rises in the steam condenser 3 upwards, wherein the cooled water is conducted in the form of droplets in countercurrent. In this process, the water droplets are cooled and the hot steam substantially returned to a liquid phase. The warmed up water 17 is guided by the influence of gravity in the sump 9. The water in the sump can have a water temperature of up to 100 ° C. About the pump 10, the heated water is fed to the heat exchanger 11. The heat exchanger 11 is connected to a consumer, which may be, for example, a space heater. Via the supply line 13, the cooled in the heat exchange water is passed to the steam condenser. From the supply line 13 individual lines go to the levels 4, 5, 6 and 7, each having a sprinkler. The cooled water is fed via the sprinklers in the circuit back to the steam condenser 3. On the top of the steam condenser 3 is an exhaust pipe 8. In addition, a second exhaust pipe 14 is provided, which is then used when, for example, the steam condenser is repaired.
